1 Test Results from the AHRI Low GWP AREP (Alternative Refrigerant Evaluation Program) Bus Air-Conditioning System Drop-In Tests of R134a and R407C Alternative Refrigerants In Bus Air-Conditioning Units
2 Acknowledgements Thanks to the following companies for supplying the refrigerant samples tested: - Honeywell Mexichem Daikin To those who performed the work: - Markéta Kopecká - Michal Hegar - Prague Lab Team - Vladimír Šulc 2
3 Purpose Evaluate selected alternative refrigerant blends to determine their performance as drop-in replacements for R134a and R407C in bus air-conditioning systems 3
4 Summary Two different low GWP refrigerants were tested as possible replacements of R134a in a bus air conditioning application. Two different low GWP refrigerants were tested as possible replacements of R407C in a bus air conditioning application. Testing was run at the same combination of conditions (ambient temperature / box temperature / box air humidity/ compressor speed/evaporator fan speed) as current units charged with R134a or R407C. 4

17 Conclusion Refrigerants with lower GWP values can be formulated to replace R134a and R407C in bus air-conditioning systems The refrigerants tested are not true drop-in replacements. Use of the current alternatives will require changes to the design of existing bus air-conditioning systems Several refrigerants tested are rated A2L and risk assessment work must be carried out to determine safe operation in the bus air conditioning application 17

25 Comments on results Different parameters were observed, evaluated, and compared to the same parameters obtained with R134a or R407C. - Cooling capacity: R134a - AC5 has lower capacity at all conditions except two. The two conditions are within the experimental error of the test facility. - N-13a has lower capacity at all conditions. R407C - L-20 has slightly higher or same capacity at all conditions except one. The one condition is within the experimental error of the test facility. - D52Y has lower capacity at all conditions. 25
26 Comments on results - Unit COP: R134a - AC5 has lower COP values at all conditions except one. - N-13a COP varies from -4% to +3%. Considering test facility accuracy, COP is similar to R134a. R407C - L-20 has slightly higher COP values at all conditions except two. - D52Y COP values are lower at all conditions. 26
27 Comments on results - Discharge pressure: R134a - AC5 has higher pressure at all conditions except two. The pressure differences vary from -1 psid to +15 psid. - N13a has the discharge pressure lower at all conditions. The pressure differences vary from 0 psid to -10 psid. R407C - L-20 has generally higher pressure at higher box (104 F & 120 F) and simultaneously higher ambient conditions (104 F & 120 F). The pressure differences vary from psid to psid. - D52Y has the discharge pressure lower at all conditions. The pressure differences vary from -2 psid to -45 psid. 27
28 Comments on results - Discharge temperature: R134a - AC5 has generally lower discharge temperatures (to -15 F). - N13a has lower discharge temperature at all conditions (to -26 F). R407C - L-20 has generally higher discharge temperatures, especially at the combination of lower box and ambient temperatures (to +30 F). - D52Y has generally lower discharge temperature, especially at the combination of lower box and ambient temperatures (to -38 F). 28
